She received her PhD from the University of Cambridge in 1999 and has led an independent research group since 2005. Her group investigates signal transduction processes in T lymphocytes with advanced fluorescence microscopy approaches. She has published more than 130 peer-reviewed publications including in Nature, Cell and Nature Immunology.

Jul 22, 2017 · EOC20 cells were transduced with a viral vector for imaging active cyclic adenosine monophosphate (cAMP) (Montana Molecular, Bozeman, MT, USA). Cell transduction was performed in accordance with the manufacturer's protocol for the red fluorescent cADDis cAMP assay 48 h before imaging.

The regulation of protein synthesis in this system is known to be translational since extracts prepared in the dark have identical pools and quantities of mRNA as extracts prepared in the light (Kirk and Kirk, 1983). Exploration of the mechanism of translational regulation has led us to consider the importance of signal transduction pathways. Here we discuss the effects of E2F activity on signal transduction pathways and its potential biological consequences. E2F regulates expression of components of signal transduction pathways. In the signal transduction pathway, a stimulus is converted and amplified during the transduction phase. I. Sensation – This term refers to an action potential that has reached the brain and “sensed” the nerve impulse. II. Perception – This term refers to the integration (“thinking about it”) of a received action potential. III.

Signal transduction is the process of transferring a signal throughout an organism, especially across or through a cell. The signal transduction pathway of touch and vision works in the same way that many nerve signals do. Instead of creating a second messenger or processing a signal internally, the...A hormone is a chemical substance, produced by a gland and carried in the bloodstream, which alters the activity of specific target organs. An example of this is the release of the hormone ... TNS4 (tensin 4) encodes an actin binding protein involved in cell migration, cartilage development and in connecting signal transduction pathways to the cytoskeleton (Van de Werken et al., 1993; Lo, 2004). Feb 18, 2003 · Many neuroscientists desire to understand events that occur at the synapse. We would like to know in exacting detail how receptors respond to neurotransmitters and neuropeptides. Communication based on autoinducer 2 (AI-2) is widespread among gram-negative and gram-positive bacteria, and the AI-2 pathway can control the expression of genes involved in a variety of metabolic pathways and pathogenic mechanisms. In the present study, we identified luxS , a gene responsible for the synthesis of AI-2, in Streptococcus gordonii , a major component of the dental plaque ...

EGF Signal Transduction Pathway - The epidermal growth factor (EGF) is a peptide primary messenger that utilizes a signal transduction pathway to stimulate the differentiation, growth and division of epidermal and epithelial cells. Two EGF molecules bind onto the EGF receptor, one on each side of the extracellular domains. Most processes of signal transduction involve ordered sequences of biochemical reactions inside the cell, which are carried out by enzymes, activated by second messengers Unicellular organisms may also respond to environmental stimuli via the activation of signal transduction pathways.
